'sheli: C are mounted a. clutch E, and gear wheels E and E 'arrsn ed respectively upon '0 posits sides oftie clutch. The clutch is adapted to slide upon the shaft C in the usual manner and to be brought into engagement with either of the gear wheels is and E which are loose upon the Arranged below the shaft C-is a shaft F upon which are fixed cam disks F and F coves F? soclFf.

The e aeration of the evice is asfollows fcontinuouslg rotst'ed. $21.1. whee E md E are loose upon the she t. Assumir'lg that the bed A has reached:v the of its'gi'avel; in one direction; and'lhst' thecalm di'slfF is in the pesitlofi shown in Fig. 1, the'clutch K will thenmove" toward the arms B andshift the shaft D bringing the roller D? int'o o. gagement with the oove'B in, one of the arms B. The cam visks F will have reached such 5.- position, that the-clutch will be dis-' engaged from both of the gears E i'andfE I and both will then be idle. I Itwillbe oh vious that thepiu K will also look the shaft D to the shaft C and ;that"the arm'D, w-ifl be revolving and as 'the roller l) is" in en a emeut with the groove B the bed A I stscte lupou its traveliu the-directio1i .op-

t u al rs- Q seamen posite to that it had previously taken. I lm mediately after this movement however, the further rotation of the cam disk F willlslide the shaft D in the opposite direction and 5 withdraw the roller D Irom engagement with the groove 13 and at the same time the cam disk will throw the clutch E into engagenient with one otthe gears E or E according to the direction of travel of the table endthe further movement of the table will be eon tinned by the rotetion'of the gear. When the table reaches the limit of its travel again this operation will be repeated substantially as above described.

15 It will be obvious from this descrip tion that the strain occasioned by stopging the travel. in one direction. and starting it in the other, will be thrown upon the shaft D and its arts and not 11 on the gears E and E v an rack bars A an 13.

Havin thus fully described my invention what I o aim' as new and desire to secure by Letters Patent,is:

2e bedmovable in opposite directions, of

mounted gear wheels, of oppositely arranged reekbars supported by the bed and adapted to be engaged res eetively by said I gear wheels, a clutch sli ably mounted between said gear wheels and adapted to enga e. alternately with each, means for holdin {said f clutch out of engagement with both 0 said gears when-the bed reaches its limit-of travel in either direction, and means for starting the bed upon a return'niovement independ 3 ently of the gear wheels. 7 v
